Hi, I have been trying to get some debug information from a point in the kernel where I am seeing some errors. I am actually trying to figure out how a particular point in code was reached. Here is what I did: if (case_when_error_happens) { extern int sprint_symbol(char *buffer, unsigned long address); for (i = 0; i < depth; i++) sprint_symbol(bt[i], (unsigned long)__builtin_return_address(i)); printk("%s < %s ...", bt[0], bt[1] ...); } I get most of the information I want. But I was wondering if there was any other cleaner, more straight forward way to do this. Thanks. -Harish
